One problem many people have with the NBA is the perception that players don’t exactly kill themselves in the name of defense. The 82-game regular season is more of a marathon than a sprint, so it’s understandable if some energy budgeting takes place from time to time. But O.J. Mayo’s defense during last night’s Milwaukee Bucks-Denver Nuggets game is indefensible.

Instead of guarding Randy Foye, Mayo decided to casually tie his shoe for a solid seven seconds. This prohibited him from playing help defense — or even yelling help — as the Nuggets scored an easy bucket.
